Outline

This IC, developed for use in CD-ROM drives, combines a 3V regulator adapted to low power consumption with a much-sought reset function (regulator input monitoring), with internal delay circuit, set to detect 4.2V.

Features

1. Large output current 300mA max.

2. High ripple rejection rate 80dB typ.

3. Internal thermal shutdown circuit.

4. Internal current-limiting circuit.

5. Adjustment-free reset detection voltage 4.2V typ.

6. Easy to set delay time from voltage detection to reset release.

7. Operating temperature range and ripple elimination rate are available separately for 3 ranks.

Applications

1. CD-ROM drive

2. Optical disc drivers
